167 patients were randomly assigned to device groups. Haemodynamic data, airway leak pressure, leak volume, success rates and postoperative complications were assessed.

This study compared the performance of i-gel® and cLMA airways in 50 healthy adult patients. The success rate on the first insertion attempt was significantly lower in the i-gel® group. Overall success after two attempts did not show a significant difference, although a change of device size was allowed. Leak pressures and fibreoptic view of the vocal cords were significantly better with the i-gel®, with the two devices producing leak pressures of 20 (i-gel®) and 17cm H2O (cLMA). 14 patients needed a change in i-gel® size.

This study compared i-gel® to two other supraglottic airways in respect of haemodynamic changes, including heart rate, systolic and diastolic blood pressure, mean arterial pressure and rate pressure product. The authors concluded that ‘i-gel® effectively conforms to the perilaryngeal anatomy despite the lack of an inflatable cuff, it consistently achieves proper positioning for supraglottic ventilation and causes fewer haemodynamic changes as compared to other supraglottic airway devices.’
